Engine Rebuild & Overhaul

An engine rebuild is the largest job a workshop takes on, and the one that most separates a workshop from a parts-fitter. It is measurement work: every clearance checked against the manufacturer’s figure, not against what looks about right.

CPA Motorworks rebuilds engines in Limassol with a lathe on the premises, so machining is done in-house rather than sent out. Every rebuild is measured against the manufacturer’s clearances and given a final check before the car is returned.

We have a machine shop, not just a workbench

There is a lathe on the premises. That matters more than it sounds: a workshop without one has to send every machining job out, wait on somebody else’s schedule, and trust work it did not watch. Doing it here means the tolerances are ours to answer for.

The honest conversation first

A rebuild is not always the right answer. Depending on the car, its mileage and what has failed, replacing the engine or moving the money into a different car can be the better decision. We would rather have that conversation before the engine comes out than after.

Nothing leaves until it is right

Every completed job gets a final check before the car goes back to its owner. On a rebuild that is not a formality — it is the whole point.

• Knocking or rattling from the engine
• Blue or white smoke from the exhaust
• Losing oil or coolant with no visible leak
• Overheating, or a head gasket already diagnosed elsewhere
• A timing chain that has started to rattle on start-up

What does an engine rebuild actually involve?

The engine is stripped, cleaned and measured, worn components are machined or replaced, and it is reassembled to specification. The measuring is most of the work.

How long does an engine rebuild take?

Weeks rather than days. Stripping and measuring is the quick part; machining and parts set the timescale, and a job waiting on a crankshaft regrind or a set of pistons cannot be hurried without paying for it later. We put a realistic timescale on the work before it starts.

Is a rebuilt engine as good as new?

In the parts that wear, yes: bearings, rings, seals, gaskets and anything worn beyond its limit are renewed or machined back to the manufacturer’s figure. The block and head are the original castings, kept because they measure within their limits, which is why a rebuild costs a fraction of a new engine.

Does a rattling timing chain mean the engine needs rebuilding?

Not if it is caught early. A stretched chain and its guides can be replaced as a job in its own right; left until it jumps a tooth, the pistons meet the valves and the job becomes a rebuild. That is why the rattle is worth acting on the week you first hear it.
